A 760-µF capacitor is connected in series to a 150 V power supply and a 1.5 k? resistor. At t = 800 ms, the switch is flipped such that the capacitor is in series with only the 175-mH inductor.  At the moment the switch is flipped, what is the voltage (potential) across the capacitor? How […]

Write one page paper explaining the ohms law and its application in every day life.

Write up cogent responses to the following questions using complete sentences that make sense. You may use online lectures from earlier in this course, outside sources of information, the textbook, and may consult me or classmates, but must write your answers in your own words. You will be graded on whether your responses are correct, how well they are written, and how completely the question is addressed in your response. This is from textbook Physics concepts & connections fifth edition by Art Hobson 1. If you drive through a turn at constant speed, what direction is your acceleration? Based on a free body diagram identify what force is most directly responsible for the car’s acceleration in the turn. What happens to the acceleration if a car is slowing down at the same time as it is going through a turn, answering as completely as possible. Would the car need more or less force to slow down in a turn versus coasting through? 2. Let’s say that a car company has managed to double the gas mileage on its cars in the last twenty years, but now aims to double it again. Based on the second law of thermodynamics, does this seem likely? Is there a way to appear to double the gas mileage of a car that would violate the calculated maximum predicted by the second law of thermodynamics without actually violating that law of physics? Describe how this might be done or possibly is already being done. 3. What energy transformations are involved in: (a) a photovoltaic solar panel trickle charging a battery, (b) a microwave oven reheating some coffee, (c) a climber climbing up a sheer rock face, (d) a battery powering a lightbulb, (e) a slingshot slinging a small rock at a wall. Make sure to answer in terms of specific energy types rather than broad categories of energy types and note that there could be more than two energy types involved in some cases. 4. Sound and light are both waves. Describe at least three distinct phenomena or characteristics that sound and light have in common and are connected with the fact that both are waves. Describe at least three examples of ways in which sound and light are different.

Our society runs on vast quantities of cheap energy, most of which is obtained from burning easily extracted fossil fuels. But as our reserves of these “easy” fuels diminish, we are going to be forced to make increasing use of other sources of energy, such as more “difficult” fossil fuels and various types of nuclear and renewable energy. Your assignment is to do some research and write a brief paper on ONE of these other energy sources. In your paper, you will consider such factors as 1) availability of the energy source 2) the technology needed to make use of (“extract”) the energy source, 3) what the energy source may be useful for, 4) what the energy source may not be useful for, 5) the environmental impacts of using the energy source, 6) the long term sustainability of the energy source, 7) and whether the ease or difficulty of using this source makes pursuing it worthwhile.

The politicians and the news media often warn us of an impending energy crisis. After visiting the website for the United States Energy Information Administration (located within the weekly readings) post your thoughts on the following: What is the energy crisis? What can be done about the energy crisis? How do you feel about the energy crisis? This needs to be 5-7 complete sentences, reference any information used or cited. Use the website in the attached document.

Find a current news article that is directly related to recent research in physics. USE THIS ARTICLE -> https://news.berkeley.edu/2020/08/17/new-center-to-focus-on-physics-of-ultra-dense-neutron-stars/ 1- Very briefly summarize the work and how it is related to physics    (one short paragraph or less). 2- List which one or two branches of physics are involved with the work that is discussed in the article. 3- Don’t forget to reference or attach your article

Task 1 (3 points) A bent bar lies in a vertical plane, the x-y plane, and is affected in addition to the attachment by two forces Poch 3P, and a moment M1 = 2P · a.P = 1kN, a = 0.5m and  b= 30 °. Decide in vector form: a) the force resultant b) the torque resultant with respect to point O Task 2.  A sleeve Cmed massanm = 100kg can slide on the smooth fixed rod AB, which has the length l. It is held up by a wire CD. What is the force in the wire for the geometry (a = 0.5m) and the position that the figure next to it shows?

Related Diversification. Related Diversification is the most popular distinction between the different types of diversification and is made with regard to how close the field of diversification is to the field of the existing business activities. Related Diversification occurs when a company adds to or expands its existing line of production or markets. For this assignment, consider a company of your choice. Assume your company opted to pursue a strategy of related diversification and respond to the following questions. Explain why company has chosen this related diversification (by referring attached related 1, related 2 and incorporate points from attached and elaborate) What industries or product categories could if diversify into that would allow it to achieve economies of scale? (refer attached related 3 and incorporate the points in attachment and elaborate) Identify at least two or three such industries or product categories? Describe the specific kinds of cost savings that might accrue from entry into each (by referring related -3 and incorporate the points as stated in attachment and elaborate) Incorporate our coursework (Thompson text and other material) from this week into your above responses. Submission Details: Your analysis should be 500 words or more. Incorporate a minimum of at least one course (Thompson text) and one non-course scholarly/peer-reviewed source in your paper and give the complete URL from where these references have been retrieved. All written assignments must include a cover page, introductory and concluding paragraphs, reference page, be double-spaced, and proper in-text citations using APA guidelines. Follow all the above points without even missing one point

Using components determine the sum of a  +  b   if  a  = 3 m [N 30° W] and  b  = 2 m [N 10° E]. Note: Since the use of components is a useful strategy for word problems later in this course, your solution must make use of vector components.
